-' This invention vrelates to improvements in the packing, vending and dispensing of greases -suitable for automotive use, andparticularly to a non-rellable grease package or can embodying means for manually expelling the contained grease. u

The object of this inventionfis to vprovide `a container or package for grease whereby grease may be packed by the manufacturer in 4cans of denite capacity units and in graded quality and thecan marked with its capacity orwe'ightand' the 'grade thereof, together with its source of origin in a manner whereby the purchaser `willreadilyl obtain such definite information, and thereby facilitate sale andpurchaserof grease in standard amounts and qualities. l rAnother object relates to the dispensing of grease from originalfactory packed containers inA definite amountsand known grades, directly to the portion ofthe motor v ehicle requiring it, such as its transmission ordifferential, without contamination or loss, by dispensing means embodied in the can in which the grease is packed, without the aid of tools or other like mechanical aids, so that a purchaser may readily carry out the operation himself, or without the requirement of a service station for the installation of relatively expensive equipment or the carrying of excessive supplies of grease of varying grades.

A further object relates to the packing of grease in cans of standard sizeand graded quality by the manufacturer with integrally contained manual dispensing means whereby the can after use and by the dispensing operation is operatively destroyed so that it cannot be unscrupulously refilled.

Other objects relate to various details of economy and construction which will be apparent from a consideration of the following specifica.- tion and drawing, wherein:

Fig. 1 is an elevation of our grease dispensing package, with parts broken away.

Fig. 2 is a vertical section on the line 2 2 of Fig l, showing the plunger partially depressed, and the nozzle closure removed and a delivery hose attached to the nozzle.

Fig. 3 is a detail in perspective of a modified form of plunger.

Fig. 4 is a detail in perspective of our preferred form of packing ring.

Fig. 5 is a vertical section similar to Fig. 2, embodying the form of plunger shown in Fig. 3.

Referring to the drawing, the reference numeral I D indicates the can body which preferably is cylindrical sheet metal body, but may be made of` other..V materials such asbreboard and v the like, andmaybefof other shape, such vas rectangular. The .body seam I I-,is formed onwthe exterior ysurface fof the :can so that the-'interior thereof, issmoothvto permitheaseyin operationof the .plungerv` which, `will Abe hereinafter .deeA scribed.; i f- The head I2 of thewcanrislsecuredfto the body in,.the-, conventionalmanner by means of rthe, crimped seam I3,.and.the bottom edge of. the. can is formed with the; external seam I4 to yield asmooth edge and leavean internally uniform smooth. surface. t Extending` from.,the head I2. eccentricallynthereof and adjacent vto its periph--` eral edge, is '.the; tapered `spout I5, closed rpref.

erably .bymea'ns vof thethreaded cap I6.

In` place. ofrthe conventional bottom clcvnsure.l

we provide. theplunger ITI-,formed with a periphf-z eral seatj, and which fits snugly intothey can body and. is slidable therein. Seated in the seat I8 is'the sealing/,or packing element I9, which.

may be of any suitable material, but preferably is of sponge rubber so that grease contained ln the can may enter its pores and cause it to distend and thereby enhance its sealing action .and 1n addition aid the action of the plunger. If desired the sealing el/ement maybe lightly adheredv to its seat I8.

Extending from the outer face of the plunger I'I 'is the handle 20 whereby the plunger may be manually operated. For the purpose of storing the above set forth cans after they are filled with grease, to prevent leakage, or to prevent accidental .displacement of the plunger, we preferably place a small amount of external sealing material, such as sealing wax, at the peripheral edge of the plunger I'I, where its seat I8 meets the body I0, as at v2|, or in place of sealing wax, small amounts or spots of solder may be used, and in any event the amount of such external sealing material or its composition is such as will readily part or bel broken upon manual inward depression of the plunger, and will not impair its normal operation,

Although we have shown in Fig. l the handle 20 extended outwardly of the cam body and the entire can lled, it will be understood that the` cal, due to the fact that withdrawal of the plunger`- from its depressed position will cause disengagement of the sealing ele and the general inabilit l.to properly reposition the plunger I1 in a plane at' right angles to the longitudinal axis of the can to obtain the snug and leakproof fitting of the parts as originally assembled. 1 l

As shown by Figs. 3 and 5, We have provided additional means to prevent re-lling of the can after use by means which destroy the can head. Thus the ymodified plunger I1 which is otherwise similar to the construction of plunger l1 above set forth and is operative in a like manner, is provided with a knife blade 2.3 secured to its inner face adjacent to its center as at 24. As the plunger l1 is depressed during the dispensing operation the knife 23 destroys the can by cutting va slit in the head l2, and in addition to thus destroying the kcan is an indicator of coml plete dispensing of Iits contents.

We claim as our invention:

,lfA grease dispenser comprising a body adapted to contain grease, a head Xedly secured thereto, a spout extending from said head adjacent its peripheral edge and provided with a terminal removable closure, the said closure being adapted to'be replaced during dispensing operation by a delivery conduit Iengageable to said spout, a bottom closure slidably positioned Within said body and adapted to act as a plunger and slidably completely to' said head and provided ent I9 from its Seat-I8,

Vvvith a handle for manual actuation thereof, an

inner peripheral seat formed on the face of said plunger, and a packing element of substantially rectangular cross-sectional area positioned in said seat in sealing engagement with said body with one surface exposed to the contents thereof, the said packing element comprising porous expansible material adapted to be swelled and the sealing Vvaction thereof enhanced by means of liquid pressure.

' 3'. A grease dispenser comprising a body adapted to'icontain grease, 'a headxedly secured thereto, a spout extending from said head adjacent its peripheralv edge and provided with a terminal removable closi.1re,a"bottom closure slidably positioned within said body and adapted to act as a plunger and provided with a handle for manual actuation thereof, an inner peripheral seat formed on the face of said plungenand `a packing element positioned in said seat in sealing engagement with said body and said bottom closure element, the said packing element having a surface area exposed tothe interior of said body in a plane substantially parallel -to the face of said plunger comprising sponge rubber adapted to be swelled and the'sealing action thereof enhanced by means o'fgrease contained in said body during the dispensing thereof.
